Hopefully the link works, the previous owner of my tank drilled holes in the return line behind the weir/overflow, would those rubber plugs be reef safe? I'd like to plug the holes as a lot of already filtered water is flowing right back into the sump, worst case is I have to rebuild the return pipe but I'd much rather not go that route.
